13. This passage from Isaiah is also explicit: 'Thy dead men shall live again.' If the prophet had wished to speak of a spiritual life, if he had intended to say that those who had been executed were not dead spiritually speaking, he would have said: 'They are still alive,' and not 'They will live again.’ In the spiritual sense these words would be a contradiction, because they imply an interruption in the life of the soul. In the sense of moral regeneration they would be a denial of eternal suffering because they establish in principle that all those who are dead will one day come back to life.
